Title: Variable attenuator
Inventor: KAJIWARA KOJI
IPC: H01P1/22
Filed: 1989-07-25
Abstract: PURPOSE:To easily select a desired attenuation depending on the ON/OFF state of a switch by connecting a power distributer and a power synthesizer via the switch. CONSTITUTION:Switches 3a-3e are connected between output terminals 7a-7e of a Wilkinson power distributer 1 and input terminals 3a-3e of a Wilkinson power synthesizer 2 respectively. The switches 3a-3e are realized by on/off operation of a PIN diode 21. A voltage is caused across resistors 6a-6d of distributers 5a-5d by the on/off operation of the switches 3a-3e and the current caused by the voltage is consumed entirely in the resistors 6a-6d because the wilkinson type is adopted for the distributer 1. This is caused in the resistors 6a-6d of synthesizers 10a-10d. Thus, the circuit withstands high output power.

Title: Transmission line switching device
Inventor: SASAI TOSHIHIKO
IPC: H04L1/22
Filed: 1985-08-31
Abstract: PURPOSE:To avoid unnecessary switching and restoring operations of transmission lines for interrupted data break on transmission lines by giving a hysteresis to data reception to restore transmission lines only for continuity of several frames. CONSTITUTION:Data of a digital signal is transmitted to an internal device 14 through a main transmission line 1 and a gate 10. As long as data is received continuously from the main transmission line 1 by a receiver 3, the overflow output of a counter 6 is not outputted from a terminal Qn. Meanwhile, a frame signal is continuously inputted to the CLK terminal of an address counter 61, and the overflow output is outputted from a terminal Qm to a set terminal S of an FF 8, and the gate 10 is held in the conductive state. If data reception from the main transmission line 1 is broken, the counter 6 is overflowed to reset the address counter 61. AS the result, a gate 11 is made conductive to receive data from an auxiliary transmission line 2. When the main transmission line is restored thereafter and is broken again after reception of m-number of frames, the gate 10 is not opened because the overflow output of the counter 61 is not outputted.
